Calculating IV Titration in ml/hr
 Example 1
To lower BP, nitroprusside in dextrose 5% in water is to be
titrated 15-200 mcg per minute. The IV solution was prepared by
adding 50 mg of nitroprusside to dextrose 5% in water. The final
solution contains a total volume of 250 ml. You should infuse the IV
solution at a rate of ___ to ___ ml per hour.
To find the ml/hour:
Step 1 – Write down dosage rate
Step 2 – Write down IV concentration
Step 3 – Convert if needed
Step 4 – Reduce the units
Step 5 –Perform the math
